Stem cells including cancer stem cells (CSC) divide symmetrically or asymmetrically. Usually symmetric cell division makes two daughter cells of the same fate, either as stem cells or more differentiated progenies; while asymmetric cell division (ACD) produces…

Cells within the retina synchronize transmitter release across their output synapses in the dark, reducing the impact of noise generated at these synapses and allowing light-dependent signals to be transmitted with minimal added synaptic noise.

Intel, one of the largest semiconductor chip manufacturers in the world, has a disturbing history when you look at the company and exactly what’s going on with the hardware it produces. For starters, Intel is basically an Israeli company, despite its headquarters…
